I don't know if I would say "cinema quality" but you can get impressive, immersive sound from a soundbar these days.
Some quick recommendations, in order of ascending price:
Vizio 36" 5.1.2 (also available in a 3.1.2 setup, but with a smaller sub and the street price is higher than the one with surrounds)
Sony Z9F (3.1, no upfiring speakers, but can add on rear surrounds)
Vizio 46" 5.1.4 (also available in a 3.1.2 without rear surrounds or upfiring speakers, same size sub)
Sony ST-5000 7.1.2 (no rear surrounds, so it's doing some DSP, but sound is supposed to be great)
Samsung N-950 7.1.4 (highest number of drivers, but it's expensive and the 46" Vizio is supposed to be competitive in performance if you can live with only one HDMI input)
